Real-time sense data querying

A technique is directed to handling a storage device error within storage equipment that includes a client and a driver. The technique involves providing an IO status communication from the driver to the client. The IO status communication indicates status of an IO operation performed by a storage device coupled with the driver. The technique further involves, in response to the IO status communication indicating that an error occurred while the storage device performed the IO operation, providing a query communication from the client to the driver. The query communication requests sense data corresponding to the IO operation. The technique further involves, in response to the query communication, providing the sense data corresponding to the IO operation from the driver to the client.
